正则表达式：初始文本后的多个匹配项 [英] regex: multiple matches after initial text

问题描述

我正试图在一些初始文本之后匹配一组匹配：


mytext：some" " somethingelse" 另一件事

可能是另一件事

（？：mytext :)（？< mymatch> ["] {1,1} [^ ;] + ["] {1,1} [\ s |] +）+


我只得到最后一个可能是另一个。我希望将所有值与

引号组合在一起，因此在（）之后的+。


这可能吗？

这可能吗？

正则表达式正则表达式=新正则表达式（@"

（（？< mymatch>（？< =""）\ w + \\\ * \ w + （？=""）| [^ \s""] +））"，

RegexOptions.ExplicitCapture）;


测试输入：

某事 " somethingelse" 另一件事 可能是另一个


测试输出：

mymatch =？某事？=

mymatch =？somethingelse？=

mymatch =？另一件事？=

mymatch =？也许是另一回事？=

感谢您的帮助。


是否可以在初始匹配后定位此匹配（因此我只是

在文本mytext：之后匹配"''s，而不首先拆分字符串？


我敢肯定我能使用带有IndexOfmytext：的SubString，但是如果可能的话，我更愿意用RegEx做这个

。


我是使用300mhz处理器在PPC上工作，并且必须在案例陈述中做大量的这些内容。它有一个运行

循环的线程，我真的需要尝试尽可能小。


再次感谢。

Hello Chance，

mytext：" something " somethingelse" 另一件事
也许是另一件事

也许你想要一个更通用的方式：

正则表达式正则表达式=新的正则表达式（@"（？< =""）（\ s * \w + \ * *）+（？=""）"）;

foreach（在regex.Matches中匹配匹配（inputText.Text））

outputText.AppendText（match.Value +" \\\\ n"）;


所以你也得到了另一个第三个令牌字样。等等。
ciao Frank

I''m trying to match a set of matches after some initial text:

mytext: "something" "somethingelse" "another thing"
"maybe another"
(?:mytext: )(?<mymatch>["]{1,1}[^"]+["]{1,1}[\s| ]+)+

I only get the last one "maybe another". I want to get all the values with
quotes as a group, hence the + after the ()''s.

Is this possible?

Regex regex = new Regex(@"
((?<mymatch>(?<="")\w+\s*\w+(?="")|[^\s""]+))",
RegexOptions.ExplicitCapture);

Test input:
"something" "somethingelse" "another thing" "maybe another"

Test output:
mymatch =?something?=
mymatch =?somethingelse?=
mymatch =?another thing?=
mymatch =?maybe another?=

Thanks for the help.

Is it possible to target this match after an initial match (so that I only
match ""''s after the text "mytext: "), without splitting the string first?

I''m sure I could use SubString with IndexOf "mytext: ", but I''d prefer to do
this all with RegEx if possible.

I''m working on a PPC with a 300mhz processor and have to do a large number
of these inside a case statement to begin with. It''s got a thread running a
loop and I really need to try and be as minimal as possible.

Thanks again.

Hello Chance,

mytext: "something" "somethingelse" "another thing"
"maybe another"

maybe you want it a more generic way :
Regex regex = new Regex(@"(?<="")(\s*\w+\s*)+(?="")");
foreach (Match match in regex.Matches(inputText.Text))
outputText.AppendText(match.Value+"\r\n");

so you get also the words "another third token" etc.
